Solved Email authentication failure
As of yesterday none of my email accounts on the Cloudron accept authentication. This is happening on multiple computers using different clients (Thunderbird, Kmail) and possibly happened after trying to install Sogo yesterday. It is also happened simultaneously across six different email accounts.
I can send email though.
According to Email settings - all the accounts are green., domain is correct, there is enough space.
According to the event log - the only things that happened that was usual was installing sogo and then changing its domain from mail.xxx.xxx to webmail.xxx.xxx but it wasn't working on mail.xxx.xxx to begin with.
There were other things installed an uninstalled but nothing to do with mail but previous to sogo I tried to install lychee which worked the first time but then failed to find the api on a second install.

Do you have any log output or error message with error code? You can check the log of your Cloudron mail server at
Can you install Roundcube and try to log in with an email address and the password of the corresponding owner?
Have you tried to restart your server? As far as I know, the mail server runs completely independently of any installed apps. Did you change the dashboard or mailserver domain? Just some ideas....
@subven Mail server domain is the same, I checked that.
I didn't try roundcube but I did try rainloop yesterday when sogo wasn't working. No go.
I tried restarting the server.
The logs make no sense to me. If I refresh an address in Thunderbird the logs don't have my ip address or domain (except kubuntu.info) in them but there is another one that is listed by spamhaus and the rdns on the others is nxdomain...bizzare.
Here is an example
